For wheel loaders, the noise includes two parts: radiation noise and ear noise in the cab. The composition of radiated noise is relatively complex, but it mainly comes from the exhaust noise of the engine, the running noise of the cooling fan and the structural noise of the vehicle body induced by engine vibration; the noise in the cab of the loader is mainly low-frequency sound, which is composed of the engine and powertrain Structural noise induced by the resulting vibration. Components related to low-frequency structural noise include powertrain system, transmission system, body system, etc. Generally speaking, the powertrain and its related components are the main source of vibration, and the optimal combination between them is the first priority to reduce noise Task.For wheel loaders, the noise
